Out of desperation I've been going through the dmesg log to see if there's anything amiss. I found these entries, can anyone advise on the unknown mac address for the 2nd NIC..? Plainly it has got one, as its listed here.
[ 2.654377] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
[ 2.654390] r8169 0000:06:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[ 2.654403] r8169 0000:06:00.0: setting latency timer to 64
[ 2.654669] eth0: RTL8168b/8111b at 0xf8a2c000, 00:1f:1f:c0:c6:40, XID 38000000 IRQ 217
[ 2.655748] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
[ 2.655756] r8169 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[ 2.655767] r8169 0000:01:00.0: setting latency timer to 64
[ 2.655787] r8169 0000:01:00.0: unknown MAC (2f200000)
[ 2.656013] eth1: RTL8169 at 0xf8a3c000, 20:cf:30:ae:ee:e2, XID 2c200000 IRQ 216
Also what is strange is that the RTL8168 NIC is the onboard one, which as far as I know is setup as eth1, the PCI NIC is operating as eth0. The only way I managed to get LinuxMCE to install is by using the PCI NIC connected to the router. From then on its always worked like that, if I swap the cables over, then I lose internet connectivity from my core.
Later on in dmesg I see:-
[ 36.714622] r8169: eth0: link up
[ 36.714626] r8169: eth0: link up
[ 41.042621] r8169: eth1: link down
[ 41.042744] ADDRCONF(NETDEV_UP): eth1: link is not ready
[ 47.292675] eth0: no IPv6 routers present
When I loaded Kubuntu I had to install new drivers for my onboard NIC which was r8168.ko and I would have thought that this should have appeared somewhere, but I only see r8169 in the logs. Is this something to worry about?
I've tried swapping the interfaces around in webadmin, but this just brings the internet connection down, and then I can't access the dcerouter either. I think there is something amiss with the onboard nic, but how can I put it right?
Its becoming so frustrating, I only want 1 thing to work properly to give me a boost
